NOVELTY - A graphene/barium ferrite composite wave absorbing material is obtained from barium ferrite suspension having barium ferrite concentration of 0.5-5 mol/L and graphite oxide aqueous dispersion. The mass ratio of barium ferrite and graphite oxide is 9:1-2. USE - Graphene/barium ferrite composite wave absorbing material. ADVANTAGE - The graphene/barium ferrite composite wave absorbing material is economically manufactured with excellent wave absorbing characteristics, without affecting environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene/barium ferrite composite wave absorbing material, which involves preparing graphite oxide aqueous dispersion liquid by adding graphite oxide in deionized water and performing ultrasonic dispersion, adding barium ferrite to deionized water and ultrasonically dispersing to obtain barium ferrite suspension having particle size of 50 nm to 2 mu m, adding barium ferrite suspension and graphite oxide water dispersion liquid, ultrasonically dispersing, hydrothermally treating, reducing product with deionized water to wash until filtrate has pH value of 6-7, washing product and drying. The mass ratio of barium ferrite and deionized water is (0.0015-0.0135).
